This is part of a series of reports on the six projects assigned to Matrix for Google Summer of Code 2020.

View project: HTML Embeddable Matrix Chat Rooms

My name is Arnav Tiwari and I am a prefinal year undergraduate student from IIT Kharagpur and I wanted to share my amazing journey with Matrix. I am a budding open-source enthusiast and this was my first experience with Google Summer of Code. For the past few months, I had been working on a project to develop an HTML embeddable chat client under the GSoC program for Matrix. Matrix provides a highly versatile SDK for making custom clients that can be leveraged for a variety of applications, one of which is using Matrix to power an embeddable chat client. A chat client itself can have numerous forms, whether it being a live chat to a simple comments section. This project was intended to provide an easy-to-use and yet highly customizable client that can be deployed on a website with minimal effort.

My goal for the project was to have a useable project by the end of the coding period, however, as it turned out, the project was going to be tested in the real world far sooner than that. The need for an embeddable client and the feasibility of the project to fulfill this role was demonstrated during the second month of the coding period itself. The client was deployed on the website of CommCon 2020, a virtual conference on communication technologies (an apt place to be tested, coincidentally). On the days leading up to the conference and during the conference itself, I helped the organizers to set up, integrate, and troubleshoot the client when required. While the process went mostly without any hiccups, there was one small incident when the client broke during production. Since the project was still pretty early in development, I didn’t expect it to be bug-free and had anticipated the possibility of this happening. I was keeping an eye on things, which proved to be a prudent decision as I was able to fix this problem quickly and with minimal downtime. The rest of the conference went smoothly and the client performed quite well even when the number of users was quite large (A testament to Matrix’s scalability). Getting to experience this was a pleasant surprise since I never expected to have real users so soon, much less so many at once. Seeing the client being used out in the wild was a very fulfilling thing to witness. I also gained some very valuable feedback, courtesy of Dan, CommCon’s master of ceremonies.

Over the next month or so, I kept on steadily adding features and building up the client. The next big break for the project came in the form of another conference. KDE Akademy 2020. This was a big surprise as I genuinely didn’t expect to see another large conference using the project so soon. The conference was scheduled to be held after a week or so after the end of the coding period. This time, however, the integration was almost completely handled by the conference organizers themselves since it had to be integrated with their version of BigBlueButton, a web conferencing system. As the conference drew nearer, things seemed to be working out well and there was no sign of trouble. When the day of the conference finally came, however, many things seem to break simultaneously due to an apparent incompatibility with BBB. In the end, despite the numerous attempts by the conference organizers and myself to remedy the issues, they had to roll back to an older version of the chat since the risk would be too great. The organizers were understandably disappointed since they had spent a while working on the integration and had seen the great potential of using this client in place of their old chat system.. Even though It was a sad conclusion to the journey, there were still many lessons to be learned. Most importantly, even though the client might work well in standalone circumstances, ease of integration might have some room for improvement. Open-source development never truly stops and I don’t intend to give up on this project. I look forward to constantly improving it and seeing more people adopt it.

These past few months were a spectacular experience. Even before starting this journey, I knew I would learn a lot but this still managed to exceed all my expectations. I got to learn things I never would have thought I would be able to experience under GSoC. I met some awesome people along the way, I’m extremely grateful to my mentors Ben Parsons and Travis Ralston for being the best mentors anyone could ever ask for. They were always approachable and friendly throughout the entire program and I never hesitated before asking for their help. Without their guidance, all of this would’ve certainly not been possible. Lastly, I want to express my gratitude to Matrix for believing in me and giving me the opportunity to undertake this project. The Matrix community is full of talented people who will go the extra mile if you ask them for help. It has truly been a pleasure working with them and I hope to continue working with them in the future. Cheers and hope to see continue seeing you all!
